Revision 1.1, Sat Feb 23 07:00:21 2013 UTC (11 years, 6 months ago) by takayama
Branch: MAIN
hgm.cwishart of computing the cumulative distribution function of random wishart matrix
is implemented as an R function. #milestone 2013-02-23-a#.
We need several small changes and adjustments to complete this project.

\title{
The function hgm.cwishart evaluates the cumulative distribution function
of random wishart matrix.
}
\description{
The function hgm.cwishart evaluates the cumulative distribution function
of random wishart matrix of size m times m.
}
\usage{
hgm.cwishart(m,n,beta,x0,approxdeg,h,dp,x)
}
%- maybe also 'usage' for other objects documented here.

\details{
It is evaluated by the Koev-Edelman algorithm near the origin and
and by the HGM when x is far from the origin.

}
\value{
The output is x, y[0], ..., y[0] is the value of the cumulative distribution
function at x. y[1],... are some derivatives.
